The Kaweco Sport is a pocket-sized fountain pen that when posted transforms into a full-sized pen that easily fits in your hand. This solid matte black anodized aluminum fountain pen comes with a gold-plated steel nib and a gold-plated clip. As a piston filler, it uses bottled ink only.
Since 1883, there have been various systems for filling a fountain pen. Today, ink cartridges are a widespread and popular filling method. In the past, fountain pens were mainly filled using ink bottles. Besides lever fountain pens and eyedroppers, the piston mechanism has been the most important and reliable filling system. In 1937, the Kaweco Sport fountain pen was first presented as a piston filler under the name #612 and has been further developed in many different versions over the years.
A piston inside the writing instrument allows ink to be drawn directly from the glass into the integrated reservoir. This makes ink cartridges obsolete. The transparent window allows you to keep an eye on the ink level at all times.
Replacement nib units are available separately (note- these nib units are different than the normal Kaweco Sport).
